Raco MM110C Weatherproof Flat Device Cover 1 Gang Nema 3R

Product Description

The RACO MM110C is a single-gang weatherproof flat device cover designed to protect exterior electrical devices from moisture, dust, and environmental exposure. Rated NEMA 3R, this cover is built from high-impact polycarbonate with a clear finish, giving installers a direct view of the device beneath. It mounts in horizontal or vertical orientation and ships pre-configured for GFCI, duplex, and switch applications. The U-Fast universal fit adapter system supports 16-in-1 custom device configurations, and the patented quick-fit keyhole mounting system allows installation in under a minute. A gasket and mounting hardware are included. Licensed electricians install this cover as part of NEC-compliant exterior outlet and switch installations.

The MM110C is suited for residential and light commercial exterior electrical applications where a low-profile, flat cover is required. The flip and snap closure style keeps the cover flush when not in use. Its horizontal and vertical mounting flexibility makes it adaptable to a range of existing box orientations. The pre-configured GFCI layout covers the most common exterior device type, while the 16-in-1 adapter system accommodates duplex and switch configurations without additional hardware. The lockable tab feature allows the cover to be secured in the closed position when required by code or site conditions.
